Trigger hinge
A trigger hinge used in a mobile flip-up electronic device is disclosed to include a female shaft, a male shaft set mounted in the female shaft, and a trigger device mounted at the male shaft set. When the user opens or closes the mobile flip-up electronic device to rotate the male shaft set relative to the female shaft, a pushing and moving piece of the trigger device is moved forward or backward to switching on/off switch, and thereby booting up or shutting down the mobile flip-up electronic device. Thus, the invention enhances the application and convenience of use of mobile flip-up electronic devices.

1. Field of the Invention
The present invention relates to hinge technology, and more particularly, to trigger hinge for use in a flip-up electronic device to let the cover member and base member of the flip-up electronic device to be biased relative to each other and to provide a trigger function.
2. Description of the Related Art
Hinges are widely used in mobile flip-up electronic devices such as notebooks, smart phones, and etc. to pivotally connect a base member and a cover member together, allowing only a limited angle of rotation between them. However, conventional hinges for mobile flip-up electronic device simply allow two joined members to be turned relative to each other without providing any trigger function to start up the mobile flip-up electronic device.
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a trigger hinge for use in a mobile flip-up electronic device, which is capable of providing a trigger function to start up the mobile flip-up electronic device.
To achieve this and other objects of the present invention, a trigger hinge of the invention includes a female shaft, a first male shaft and a second male shaft pivotally mounted in the female shaft, and a trigger device including a rotating member that is pivotally coupled to the second male shaft, a linkage member and a pushing and moving member. During rotation of the first male shaft of the male shaft set, a first push block is moved toward or away from the rotating member, driving the linkage member to move the pushing and moving piece forward or backward in switching on or off the mobile flip-up electronic device in which the trigger hinge is used.

The female shaft 1 comprises a shaft body 11 defining a first barrel 12 and a second barrel 13 in a parallel manner.
The male shaft set 2 comprises a first male shaft 21, a second male shaft 22, a transmission mechanism 23, a first positioning member 24, a second transmission member 25, a first connection member 26, and a second connection member 27.
The first male shaft 21 and the second male shaft 22 are respectively inserted through the first barrel 12 and second barrel 13 of the female shaft 1. The transmission mechanism 23 comprises a first transmission member 231, a second transmission member 232, and a link 233. The first transmission member 231 is fixedly connected to the first male shaft 21. The second transmission member 232 is fixedly connected to the second male shaft 22. The link 233 has two opposite ends thereof respectively pivotally connected to the first transmission member 231 and the second transmission member 232. The pivoted point between the link 233 and the first transmission member 231 is at an eccentric location relative to the axial center of the first transmission member 231. The pivoted point between the link 233 and the second transmission member 232 is at an eccentric location relative to the axial center of the second transmission member 232. The first positioning member 24 comprises a first push block 241 disposed adjacent to the second male shaft 22 and defining a connection space 242. The first positioning member 24 and the second positioning member 25 are respectively pivotally connected to the first male shaft 21 and the second male shaft 22. The first connection member 26 and the second connection member 27 are respectively fixedly connected to the first male shaft 21 and the second male shaft 22. The second connection member 27 comprises a limiter plate 28 extended from one side thereof and defining a plurality of ribs 281 and a through hole 282, and a stop rod 283 mounted in the through hole 282.

In actual application, the trigger hinge can be used to switch on or off a connection port, keyboard, voice device or video device of a tablet computer or any of a variety of other mobile flip-up electronic devices. For example, the trigger hinge can be moved to trigger the switch 36, thereby starting up a voice device or video device, or retracting a keyboard to the inside of the base member 4, or moving a connection port out of the base member 4.
In conclusion, the key technology of the present invention is to let the male shaft set 2 move the first push block 241 of the first positioning member 24 toward or away from the second push block 313 of the rotating member 31 during movement of the trigger device 3 with the male shaft set 2, thereby driving the pushing and moving piece 33 of the trigger device 3 to switch on or off the switch 36.
Claims
